The best information I can find shows that Alberta's tar sands industry paid just ten cents per barrel for their climate pollution last year.

For scale, consider that the industry sells those barrels for 800 times that much: $80.

Environment Canada projects that Alberta's weak climate policies will allow the CO2 from their tar sands industry to increase so much that they will single-handedly wipe out all the CO2 cuts being made by all the rest of Canadians -- for years to come.

Figuring out just how much the tar sands industry actually pays per barrel for their climate pollution required some detective work...
